South Korean intelligence reports have raised concerns regarding the health of North Korean leader Kim Jong Un. Assessments suggest he is “extremely obese,” weighing over 140 kilograms, which places him at a “high risk of cardiovascular disease” due to lifestyle factors such as smoking and the consumption of luxury foods like caviar, foie gras, and alcohol.

South Korean lawmaker Yoon Kun-young, citing the National Intelligence Service, noted that Kim is reportedly under the constant supervision of a dedicated medical team to manage his health. Despite these risks, intelligence indicates that Kim currently shows no significant physical impairments or difficulties, noting his ability to perform tasks such as climbing stairs without apparent effort.

Speculation regarding Kim’s health is often fueled by his periodic absences from public view. Observers also point to his family history as a factor of concern, noting that both his father, Kim Jong-il, and his grandfather, Kim Il-sung, were heavy smokers and overweight, eventually dying from heart-related issues. 

International observers continue to monitor his physical well-being due to the potential for instability in a nuclear-armed state and the implications for leadership succession. This interest is further contextualized by the increasing public appearances of his daughter, Kim Ju-ae.
